QUOlN AND SIDE-STICK.

SPECIFICATION forming part of Letters Patent No. 324,699, dated August 18, 1885.

Application filed June 2, 1884.

To all whom it may concern:

Be it known that I, hIARSI-IALL J. Hnenns, a citizen of the United States, residing at J ersey City, in the county of Hudson and State of New Jersey, have invented certain new and useful Improvements in Quoins and Side- Sticks, of which the following isadescription.

My invention is an improvement in the class of quoins and sidesticks which are constructed ot'iron or other metal.

The improvement consists, first, in constructing such devices of wood and metalthat is to say, of a cast-metal band or hollow frame and a wooden block constituting the filling thereof; secondly, in providing such metal band or frame with a projection on its upper side,for use in drivingthe quoin orside-stick, as hereinafter explained.

In the accompanying drawings, Figure 1 represents both side view and plan of my improved quoin or side stick. Fig. 2 represents similar views ofaslightly-modified form. Fig. 3 is a vertical longitudinal section of the quoin shown in Fig. 2 (line a: m.) Fig. 4 is a side view and plan of a side-stick or long quoin embodying my improvement. Fig. 5 is a plan of a tormillustrating the practical use of quoins and side-sticks made in sections, which are marked by numbers indicating size.

As before indicated, my improved quoin or side-stick is composed of wood and metal.

The letter a indicates the wooden block or filling, and b the metal band or hollow frame, which is cast on and around it, so that the two parts are firmly and permanently secured together. As shown in Fig. 1, the filling a is one solid piece; but in Fig. 2 the frame I) is shown constructed with a transverse central brace or partition, and hence the filling a is in two equal parts, one part occupying the cavity on one side of the partition and the other part the space on the other side. This partition will obviously'serve to support the sides of the hollow frame I) againstlateral pressure, and therefore enables it to be made thinner and lighter than would be otherwise practicable.

On the upper side and in the middle of the metal frame I) is atransverse projection or rib, c, which serves as an abutment or rest for the shooting-stick in driving up the quoin or side-stick in the operation of locking up (No model.)

the form-that is to say, the end of the driver or shooting-stick is placed against the abutment 0, instead of the end of the quoin, as usual, and thus battering, upsetting, and consequent enlargement of the ends of the quoin are avoided. These projections 0 are preferable to cavitics,since the latter not only weaken the quoin,but become filled with ink and other substances, which interferewith the operation of driving up.

The corners d of the metal frames 11 are rounded or beveled, so that in driving them (with mallet and shooting-stick) there is no danger of gouging or abrading the surface of imposingstoue, as all metal quoins with rightangular corners and angles are liable to do.

In practice much time may be saved by numerically designating the succession or grada tion in size of the quoins, and also several pieces composingaside-stick. Thus,asshown in Fig. 5, the smallest or thinnest section of a side-stick, as well as quoin, is designated or marked by the number 1, the next in size by 2, the third by 3, and so on. In other words, the gradation in size and number correspond, so that the quoins or sections that must be used adjacently may be instantly selected and laid in line.

If in practice difficulty should. occur in selecting graded quoins from side-stick sections when lying promiscuously together, the quoins may be distinguished by a different color or any other suitable mark.

Taking my invention as a whole, it isdesigned and adapted to effect a considerable economy in material, time, and labor in ways above indicated.

XVhat claim is- 1. A quoin composed of the oblong metal band b and inclosed wooden block a, filling the cavity of the same, substantially as shown and described.

2. A quoiu or side-stick having projections from the top plane thereof for use in driving in the operation of locking up.

In testimony that Iclaim the foregoing as my own invention I affix my signature in presence of two witnesses.
